(c1. 198 -123) The invention relates to, an improvedmeans for adjusting feeder carriers usedin connection lirfectedrconveniently to take sag out of one side of the carrier to properly level the same. Also, such structure is complex and too costly. The main-object of this invention is to improve theadju'sting means for raising and lowering-these carriers.

Another object is to provide such an adjusting means wherebyboth tubular carrier supports may be easily operated upon together, or indepen'd; ently;-;as desired.

Still another object is to simplify the ,construction .andgcheapenithe cost of these carrier adjustments.

Other objects will later appear. Briefly, these objects may be attained by the structure illustrated in the drawing, wherein appears a carrier operatively supported in relation to a thresher self-feeder by means of a pair of spaced tubular supports, each of which includes a telescopically arranged, threaded shaft or rod. Each tubular support has rockably mounted thereon a nut, which has threaded engagement with the adjacent threaded shaft part. These nuts are peripherally pocketed to form a ratchet rim that is engaged by a dog or pawl operable by a hand lever to turn the nut and let out the threaded shaft with respect to the tubular support. A spring pressed toggle serves to hold the dog to duty on the ratchet. By cross connecting both hand levers on each unit, they may be simultaneously actuated upon the manual operation of one of them, and, by disconnecting such cross linkage from the operating levers, either tubular support may be adjusted independently of the other. The spring pressed toggle associated with each manually operable lever serves to control the direction of adjustment; in other words, the nut may turn either clockwise or counter-clockwise, as desired.

A self-feederis shown at 0, to which is hingedcludes a conveyer l3 for delivering material lo-adedythere-onto'into said feeder It) in a man,- nerwell understood in, the threshing art. The feeder carries at each side thereof a trussed, depending.framestructure l4 carrying a cross tie rod l5. Similarly, the .under part of the carrier l2,,includes at each side a trussed, depending frame structure l6.

Pivoted to each frame structure I6 by a pin I! is a downwardly and rearwardly extending tubu- 3O lar support or pipe I8, each of which at its rear end, as shown in Figure 3, turnably carries a sleeved nut l9 having threaded engagement with a threaded shaft or rod 26, telescoped at its other end and being pivotally connected to the cross 3 rod l5. Thus, each pipe I8 and associated threaded shaft 2|] forms a support between the trussed frame structure It on the carrier l2 and the trussed frame M on the feeder I0. There are two of such supports and they are parallel with 40 each other. Further, each support is extensible or contractible for the purpose of raising or lowering the carrier. The means for performing such adjustment will now be described,

Each sleeve nut l9 includes an integrally formed 45 flange notched at spaced intervals in its periphery toform a ratchet wheel 2!. A sleeve 22 is rockably journaled on the sleeve l9, as shown in Figure 3, each sleeve 22 including an upstanding bracket portion 23, to which is appropriately se- 50 cured a hand lever 24. Each bracket 23 for each adjusting devicel carries a pin 25, on which is pivotally mounted a bell-shaped member 26 having formed therewith at opposite sides two pawls or dogs 21. Also, pivotally mounted on the pin 55 25, for movement independent of the member 26,

is a switch lever 28 having two oppositely arranged shoulders 29 adapted alternately to engage adjacent points on the top side of the pawl 5 member 26.

Intermediately of its ends, each lever 28 has pivotally connected to it a toggle link 30 encircled by a spring 3|, which at one end is connected at 32 to the lever 24 and at its other end abuts a shoulder 33 included in the lever 28. The operating levers 24 each has a hole to receive the bent ends of a cross tie rod 34 for connecting the levers together, as shown in Figure 2, the rod' being held in place for quick detachment by means of cotter pins 35. The lever 28 and link 30 in each unit constitute a spring pressed toggle for resiliently locking the switch in over-dead-center positions to hold one or the other of the divergently spread pawls 21 in engagement with the ratchet wheel 2|. The link 34 makes it possible to operate both adjusting devices together and simultaneously when one of the levers 24 is manually manipulated. The use and operation of the improved adjusting device will now be 25 described.

Both toggle switchlevers 28 will first be flipped to the right hand position shown in Figure 2, the spring pressed toggle link 30 of each holding the right hand pawl 21" of each device in yielding 30 position in a notch in the associated ratchet wheel 2|, as will be obvious. The attendant now grasps one of the hand levers 24 and rocks it back and forth about the sleeve l9, causing each stroke to the right, as seen in Figure 2, to turn the associated ratchet wheel 2| one step in a clockwise direction, as indicated by the arrows. Thus, the nut l9 turns to thread the shaft 2|] in a direction out or" the pipe support l8. Therefore, the support l8, 2|! elongates and the carrier platform I2 is raised. As both levers 24 are interconnected by the link 34, both supports I8, 20 are simultaneously adjusted in the manner described.

In a step by step manner caused by rocking one If it is desired to lower the carrier platform carrier to a level position.

simultaneously.

l2, the switch levers 28 are flipped to the left, as seen in Figure 2, causing the left hand pawls 21 to be operatively associated with the ratchet wheels 2|. Rocking movement of the levers 24 will now turn the ratchet wheels 2| counterclockwise, as viewed in Figure 4, to shorten the telescopic supports I8, 20 to lower the carrier.

Byoppositely disposing the toggle switch levers 28, the two supports |8 can be simultaneously adjusted in opposite directions to warp or level the Or, conversely, by disconnecting the tie rod 34, each support I8 may be adjusted independently of the other. 1

From this disclosure, it can now be seen that an improved adjusting means for the purpose mentioned has been provided, which attains all of the desirable objects heretofore recited.

It is the intention to cover herein all changes What is claimed is:

1. An adjusting mechanism for afeeder carrier hingedly associated with the feeder of a thresher, said mechanism comprising a pair of extensible and contractible supports connected between the carrier and feeder, and interconnected rockable means carried by the supports" spaced supports, each of which comprises a pipe r and threaded-rod extending into the pipe-with a nut on each'rod including a sleeve into which the" adjacent pipe is loosely fitted, and interconnected I rockable means carried by the nuts forextending the supports simultaneously together, or for contracting them simultaneously together, or for extending one support and contracting the other ARNT W.
